Like the Porsche 944, we were surprised by how poorly many RX-7s fare in the 24 Hours Of LeMons (though the succeed/fail breakdown seems to be an all-or-nothing sort of deal, with few falling in the middle third of the standings). Fuel system ailments and fragile suspensions seem to be the weak points.

Green = top third of standings
Yellow = middle third of standings
Red = bottom third of standings
